【答案】Dear Mr Smith,

I'm Li Hua, a student from Class 1, Grade 3. I'm glad to hear you will come to teach us. I will give a brief introduction of our class to you.

There are 60 students in our class, including 36 boys and 24 girls. Most of us are fond of studying English, but the abilities of listening and speaking are relatively weak, especially when communicating with foreigners. Although the academic atmosphere is great, we always can't get good grades.

We hope you will give us more opportunities to express ourselves in English and enjoy more English videos in class. In addition, if a variety of English activities, such as English short plays and English speech contests, can be held regularly, our English will improve greatly.

We are looking forward to your coming!

Yours,

Li Hua
